"This is something that affects so many people," Rosenquest said, noting the organization will pool its proceeds with those from other area groups for a joint donation. "Almost everybody knows someone affected by Alzheimer's."

Rosenquest organized a similar ranch rodeo and roping event with a different organization for four years prior to starting up Saddle Up For Alzheimer's.

Alzheimer's is a progressive disease that brings problems with memory, thinking and behavior, according to the association's website. It worsens with time, and although treatment is available, there is no cure.

The three-day event begins with a ranch rodeo Friday, complete with mutton bustin' and a silent auction. Admission is $5, but children age 10 and under get in free.

Live music and a dance follow at 9 p.m. Friday and, while admission is $15, children age 10 and under again get in free.

Saturday brings a team roping event and silent auction, while Sunday offers up an exhibition and barrel racing.

Admission is free both Saturday and Sunday, and concessions are available all three days.

Rosenquest said organizers are still accepting silent auction donations. Attendees can make additional donations to the Alzheimer's Association throughout the three-day event, as well.

All in all, she said she looks forward to the coming rodeo and hopes to see a large crowd.

"We want people to come out, enjoy themselves and support the cause," Rosenquest said. "We need to find a cure."
